Sample breakdown. From 43 patients, there were 36 CSF and 46 plasma samples. There were 6 patients that had paired CSF samples and 5 patients that had paired plasma samples from both active and cured time points; the remainder were unpaired. The total number of samples for each time point is given in a breakdown of whether the samples came from patients with subarachnoid or ventricular disease. The median time from sample collection to therapy is given for each group, with a range. A negative number indicates the number of days prior to starting (for active disease) or stopping (for cure) anthelmintics that the sample was collected; a positive number indicates the number of days after starting (active) or stopping (cure) anthelmintics that the sample was collected. Abbreviation: CSF, cerebral spinal fluid.
